I'm the lousiest shot giver of all time. I've had to do it for for a long time now...and I'm still lousy at it. Dogs, horses, calves, humans...they see me comin' with a needle and they panic and stampede. Those that can hardly move, they're so sick, look at me with abject fear in their eyes.
There's no doubt that there are experts at it on this board that can give you good information. I eagerly await surefire shot instructions.
